 # build
 
-To build is easy, just import the build file in sublime_text_build.
-I coded this in sublime text so I made this build file.
-The program uses MinGW64, anyway this is not a serious project.
+There is two options for building, directly g++ command, or using CMake, I obvious recommend you use CMake.
+the project now support Unix & Linux, if you want to build under Unix & Linux, open and read the commands used in `build.bat`.
+The makefile generated used here was Ninja, so, I recommed installing [Ninja](https://ninja-build.org/).
+
+Libs necessary:
+[SDL 2.28.5](https://github.com/libsdl-org/SDL/releases/tag/release-2.28.5), [SDL Image 2.6.3](https://github.com/libsdl-org/SDL_image/releases/tag/release-2.6.3), and [GLEW](https://glew.sourceforge.net/).
+
+Also, if you are on any Linux-based OS, install with the package-manager the devel libs necessary.
+```sh
+# arch
+sudo pacman libsd2l-dev libsdl2-image-dev libglew-dev
+
+# ubuntu
+apt install libsdl2-dev libsdl2-image-dev libglew-dev
+```
